Note the code marked in red above. I agree wholeheartedly that the temp file is not needed (and suggested removing it back in post #5 in this thread), but the temp file is removed before it is appended to in the code you're questioning, so that shouldn't have caused any false high load reports either (assuming the code shown to us in post #9 is the actual code being run).

[/NOPARSE]

I can change and test Smilie


Hi anil529,
Why don't you also make the changes I suggested in post #5 in this thread (where I also proposed getting rid of the temp file) and get rid of two unneeded processes that are adding unneeded load to the system you're trying to monitor? Smilie

If you decide to try drysdalk's suggestion instead, at least note that you must change the:
Code:
if [[ "$load" > "$threshold" ]]

to:
Code:
if [[ "$load" -gt "$threshold" ]]

as noted above by vgersh99 to keep from missing reports if the load reaches 100%.
Yes I made above changes ,but still some bad data with same value is repeatedly reported from all servers.

If you want to grep only for the Average, then please omit the per-processor details -P ALL
Code:
CPU_LOAD=`sar 10 1 | awk '$1~/Average/ {print int(100-$NF)}'`
